Since we rolled out v8.1.0 and Perspective to one of our largest clients (280k tags, 70 Vision clients, + now 8 Perspective clients running inside of Vision’s Web Browser component), we’ve had non-stop issues with extremely high server CPU usage (90-100%) and incredibly slow clients (due to server CPU). We’ve been in contact with support, however have yet to find a reliable cause and solution. We removed all Alarm Status Table components from the Perspective Views as these seemed to be causing excessive and persistent perspective-worker threads (we had 1050 threads for 8 perspective session at one stage!!) Removing these has reduced this number to ~50-100 and we thought it had identified the issue as we were consistently averaging ~25% (min 16 max ~45) for 3 days but it’s recently increased to 40-50%. Unsure the reason.
Anyway, is anyone else experiencing any of these issues? Or is it just me…? Did you resolve them?
